I think, thats why the cluster stops if it is not longer possible to guarantee the specified number of copies (you want 3 copies, but there are only 2 zones left) If it is fine, that the cluster works even without the required amount of 3 copies, you can specify the nohalt option and the cluster runs even with only one node left. I prefer to have at least one zone more than number of copies so the cluster can recover from a failed node to the specified number of copies. Cheers Bastian |
